- This arm 5, as described in the aforesaid patent, transverselyoverlies the carrier rods 4, and is pivotally mounted onafixedrshaft '8along which it slides asmoved by nut 2,o'r a separate nut, on spindle 1,so as to maintain a fixed relation to end stop 3, and it acts in knownmanner to stop a carrier rod after a limited travel, as fora selvageedge reenforcement, or to detain a rod and timingly release the same, asfor proper lead of a carrier rod in plating, determined by suitablyplaced dogs Hon the carrier rods, and a cam. 9 on bar 7 acting on armextension 6. The lower edge of arm 5 heretofore has been straight toengage, when in lowered position, any rod carried dog, or said edge hasbeen recessed to clear dogs on certain rods and act only on dogs onother rods, limiting the'control of said arm and necessitatingsubstitution of another arm for change of operation.

From the foregoing description it is believed the nature of theimprovements and their manner 5 of operation'will be readily understood,and it is obvious that the specific construction set forth maybe readilymodified within the scope of the invention defmed in the followingclaims.

What I claim is: v 1. In a knitting machine having reciprocable threadcarrier rods each provided with stop members, an arm extendingtransversely of, said rods adapted to carry stop devices engageable bysaid stop members to control the movements of said rods, and means formoving said arm from rod controlling position; the combination therewithofa stop device, mounted on said arm for movement relatively to saidcarrier rods into po-- sition for selectively engaging the-stop membersof determined rods.

2.-In a knitting machine having, reciprocable thread carrier rods eachprovided withtstop meme,

bers, an arm extending transversely of said rods adapted to carry stopdevices engageable by said stop members to control the movements of saidrods, and means for moving said arm from rod controlling position; thecombination therewith of a stop device on said arm mounted formovementthereon into a number of positions for selectively engaging thestop member of any one of a plurality of said rods.

3. In' a knitting machine havingreciprocable thread carrier rods, an armextending transverse- 1y of said rods adapted to carry stop devicesengageable'by said rods to control the movements of said rods, and meansfor moving said arm from rod controlling position; the combinationtherewith of'a stop device pivctally mounted on said' arm to swingradially across said carrier rods for selectively engaging determinedrods.

4. In a knitting machine having reciprocable thread carrier rods, an armextending transverse- "ly of said rods adapted to carry stop devicesengageable by said rods'to control the movements ofjsaid rods, and meansfor moving said arm I from rod controlling position; the combination pto therewith of a stop device on said arm having a plurality of rodcontacting stops radially swingable across said rods into and out ofengaging relation with determined rods.

5. In a knitting machine having reciprocable thread carrier rods, an armextending transversely of said rods adaptable to carry stop devicesengageable by said rods to control the movevmerits of said rods, andmeans for moving said arm from rod controlling position; thecombination'therewith of a stop device on said arm havinga'pluralityof'rod contacting stops each selectively engageable with aplurality of rods.-

6. In a knitting'machine having reciprocable thread carrier rods, an armextending transversely of saidrods adapted to carry stop devicesengageable by" said rods to control the movements of said rods, andmeans for moving said arm from rod controlling position; the combinationtherewith of a stop device on said arm having said stop device inradially adjusted position for cooperation with a determinedrod; and asaid stop device to another radial cooperation with another rod.

7 8. In a knitting machine having reciprocable thread, carrier rods eachprovided with stop position for *position'for selectively engaging thestop members of determined rods; locking means for hold- 9O lever forreleasing said locking means and shifting members, an arm extendingtransversely, of said rods'and carrying stop devices engageable by saidstop members on the thread carrier rods to limit the movements of saidrods, and means for moving said arm from rod controlling position thecombination therewith of a stop device pivotally mounted on said arm forradial movement relative'to said carrier rods into position forselective- 'ly engaging the stop members of determined rods;

spring actuated locking means'for holding said stop device inradiallyadjusted position for ccoperation with the stop of adeterminedrod, and

a lever for releasing said locking means, and shifting said adjustablestop device to another radial position for cooperation with thestop ofanother thread carrier rod. r

9. In a knitting machine having reciprocable thread carrier rods, stopmembers thereon, an arm extending transversely of said rods carryingstop devices e ngageable by the, said stop members on the thread carrierrods to limit the movement thereof, and means for moving said arm fromrod controlling position; the combination therewith of a stop devicemounted on said arm for movement relative to said carrier rods intodifferent positions for selectively engaging the stop members ofdetermined rods, said arm having openings therein; a spring actuatedplunger carried by said stop device and adapted to register with andenter said openings to maintain the stop device in adjusted position forcooperation with the stop of a determined rod, and a lever operable uponthe spring actuated plunger to withdraw it from an opening to releasethe pivoted stop device andv permit the said device tobe moved toanother position for. cooperation with the stop of another threadcarrier rod.
